As shown in the figure, the cylindrical member 300 of the toner cartridge 80 includes a first protruding portion 371 and a second protruding portion 372 that protrude from the outer surface of the cylindrical member 300 toward the radial direction of the cylindrical member 300. Is provided. The discharge port 305 is formed between the first projecting portion 371 and the second projecting portion 372. In the present embodiment, the first opposing portion is connected to the upper end portion of the first protruding portion 371 and protrudes in a direction away from the second protruding portion 372 and is disposed to face the outer surface of the cylindrical member 300. A piece 373 is provided. Furthermore, a second opposing piece 374 is provided that is connected to the upper end of the second projecting portion 372 and projects in a direction away from the first projecting portion 371 and is disposed to face the outer surface of the cylindrical member 300. It has been.

  On the other hand, the first shutter 302 is also connected to one end of the shutter main body 302A formed in a plate shape and is opposed to the shutter main body 302A, and the other end of the shutter main body 302A. And a second facing piece 302C facing the shutter main body 302A. Here, in the present embodiment, the first facing piece 302B of the first shutter 302 is located in the gap formed between the outer surface of the cylindrical member 300 and the first facing piece 373. Further, the second opposing piece 302C of the first shutter 302 is located in a gap formed between the outer surface of the cylindrical member 300 and the second opposing piece 374. This prevents the first shutter 302 from falling off and enables the first shutter 302 to move in the longitudinal direction of the toner cartridge 80. In this embodiment, an elastic member 306 is provided between the first shutter 302 and the cylindrical member 300, and the first shutter 302 is urged by the elastic member 306 in a direction away from the cylindrical member 300. ing. In the present embodiment, the first opposed piece 302B and the second opposed piece 302C that function as the separation preventing portion are brought into contact with the tubular member 300 side, so that the separation from the tubular member 300 of the first shutter 302 is prevented. Yes. In the present embodiment, the elastic member 306 presses the first facing piece 302B and the second facing piece 302C against the cylindrical member 300 side, thereby causing a sliding resistance (from the first shutter 302 to the tubular member 300). The details are described later).

Next, the operation member 360 will be described in detail.
FIG. 7 is a view when the operation member 360 is viewed from the side where the cylindrical member 300 is provided. As shown in the figure, the operation member 360 is formed in a cylindrical shape, and the storage medium 17 is mounted on the outer peripheral surface. Further, the operation member 360 is provided with two insertion portions 361 that are inserted into insertion ports (described later) provided on the main body side of the image forming apparatus 1 when the toner cartridge 80 is mounted on the image forming apparatus 1. Yes. Here, in this embodiment, when the toner cartridge 80 is mounted on the image forming apparatus 1, the insertion portion 361 enters an insertion port (described later) of the image forming apparatus 1. Thereby, the movement of the toner cartridge 80 is restricted, and the positioning of the toner cartridge 80 is performed. As a result, in this embodiment, the contact between the terminal 17A (see FIG. 3) of the storage medium 17 and a terminal (described later) provided on the image forming apparatus 1 side is easily maintained.

  FIG. 8 is a diagram for explaining the insertion portion 361. Specifically, FIG. 7A shows the insertion portion 361 when viewed from the direction of arrow VIIIA in FIG. 7, and FIG. 7B shows the insertion portion 361 when viewed from the direction of arrow VIIIB of FIG. FIG. 8C shows the insertion portion 361 when viewed from the direction of arrow VIIIC in FIG.

  The insertion portion 361 has a T-shaped cross section when viewed from the side where the tubular member 300 is provided, as shown in FIG. In addition, the cross-sectional shape when viewed from the downstream side in the insertion direction of the toner cartridge 80 is a T-shape. Thus, when formed in T shape, the rigidity of the insertion part 361 increases compared with the case where the insertion part 361 is simply formed in flat form.

  The insertion portion 361 will be described in more detail. The insertion portion 361 has a flat plate-like base portion 361 A provided along the longitudinal direction of the toner cartridge 80. The insertion portion 361 has a protrusion 361B that is provided in a state of protruding from the base 361A, is disposed in a relationship orthogonal to the base 361A, and is provided along the longitudinal direction of the toner cartridge 80. Further, the distal end of the insertion portion 361 is chamfered, and as shown in FIG. 3A, two corner portions (two ends located at both ends in the width direction of the base portion 361A) are located at the distal end of the base portion 361A. An inclined surface 361C is formed at the corner. Further, as shown in FIG. 5C, an inclined surface 361D is also formed at one corner located at the tip of the protruding portion 361B. Further, as shown in FIG. 5C, the corner portion located at one end in the thickness direction of the base portion 361A is also chamfered, and an inclined surface 361E is also formed at this portion.

  Next, a location where the toner cartridge 80 of the image forming apparatus 1 is mounted will be described. Here, FIG. 9 is a perspective view showing a portion of the image forming apparatus 1 where the toner cartridge 80 is mounted. FIG. 10 is a front view of a housing member 900 that houses the toner cartridge 80.

  As shown in FIG. 9, a storage member 900 that is formed in a bowl shape and stores the toner cartridge 80 is provided at a position where the toner cartridge 80 is mounted in the image forming apparatus 1. Further, in the present embodiment, a terminal 911 (see FIG. 14) that contacts a terminal 17A (see FIG. 3) formed on the storage medium 17 on the inlet side of the housing member 900 where the insertion of the toner cartridge 80 is started. ) Is provided. Here, as shown in FIG. 10, the holding member 910 has a positioning portion 920 that is formed in a plate shape and a rectangular shape and has a positioning portion 920 for positioning the insertion portion 361. Have. 10 and 11, the terminal 911 (see FIG. 14) is not shown.

  Here, two insertion openings 921 formed in the positioning portion 920 are provided corresponding to the two insertion portions 361 as shown in FIG. 11 (enlarged view of the holding member). Here, each of the insertion ports 921 is formed in a T shape in a front view as shown in the figure, and has a shape that follows the cross-sectional shape of the insertion portion 361. More specifically, the insertion port 921 is provided with a first through hole 921A having a rectangular cross-sectional shape, which is also formed in a rectangular shape and connected to the first through hole 921A, and orthogonal to the first through hole 921A. The 2nd through-hole 921B arrange | positioned by the relationship which concerns is provided. In the present embodiment, when the toner cartridge 80 is inserted, the base 361A (see FIG. 8) passes through the first through hole 921A, and the protrusion 361B passes through the second through hole 921B.

  FIG. 12 is a diagram for explaining the insertion slot 921. Specifically, FIG. 11A shows a cross section taken along line XIIA-XIIA in FIG. 11, and FIG. 11B shows a cross section taken along line XIIB-XIIB in FIG.

  Here, in the present embodiment, chamfering is performed on the inlet portion side of the insertion port 921 where insertion of the insertion portion 361 is started. More specifically, as shown in FIGS. 1A and 1B, chamfering is performed at a location where the inner wall surface 921C of the first through hole 921A and the outer surface 920A of the positioning portion 920 intersect. An inclined surface 921D is formed at the intersection. More specifically, an inclined surface 921D that approaches the central portion side of the first through hole 921A as it goes downstream in the insertion direction of the insertion portion 361 is formed. By forming the inclined surface 921D, the insertion portion 361 can easily enter the insertion port 921 in this embodiment. Since the chamfer is also formed at the distal end portion of the insertion portion 361 as described above, the insertion portion 361 can further enter the insertion port 921 more easily.

  Although not described above, in this embodiment, both the storage medium 17 and the holding member 910 having a terminal 911 (see FIG. 14) that contacts the storage medium 17 are arranged downstream in the insertion direction of the toner cartridge 80. It is provided not on the side (back side) but on the upstream side (front side) in the insertion direction. More specifically, the storage medium 17 is provided on the rear end side of the toner cartridge 80, and the holding member 910 is provided on the inlet side of the housing member 900 where the insertion of the toner cartridge 80 is disclosed.

  Here, when the toner cartridge 80 is inserted into the image forming apparatus 1, the insertion position of the toner cartridge 80 is not constant depending on how the user operates, and a position shift occurs on the back side of the image forming apparatus 1. In this state, the toner cartridge 80 may be inserted. In other words, the toner cartridge 80 may not be inserted straight along a predetermined path, and the toner cartridge 80 may be inserted in a state of being out of this path. In such a case, if the storage medium 17 is provided on the front end side of the toner cartridge 80 and the terminal 911 is provided on the back side of the image forming apparatus 1, the contact between the storage medium 17 and the terminal 911 is prevented. There is a risk that it will not be done. For this reason, in this embodiment, the storage medium 17 is provided on the rear end side of the toner cartridge 80 in which the above-described positional displacement is unlikely to occur, and the terminal 911 that contacts the storage medium 17 is provided on the front side of the image forming apparatus 1. I am trying to provide it.

  By the way, in the present embodiment, vibration is generated by rotation of a rotating member (a rotating member used for toner conveyance) provided in the toner cartridge 80. When vibration occurs in this way, the terminal 17A of the storage medium 17 moves relative to the terminal 911 provided on the holding member 910, and the terminal 911 of the holding member 910 and the terminal 17A of the storage medium 17 are not connected. There is a risk of contact. Therefore, in this embodiment, by providing the insertion portion 361 and the insertion port 921, the movement of the terminal 17A with respect to the terminal 911 is suppressed, and the contact between the terminal 911 and the terminal 17A is maintained.

  As shown in FIG. 14, the terminal 911 is formed by bending a metal piece, and is provided so as to protrude toward the side where the toner cartridge 80 is located. When the toner cartridge 80 is inserted, the terminal 911 is pressed by the terminal 17A of the storage medium 17 to be elastically deformed and presses the terminal 17A. In such a configuration, even if the terminal 17A of the storage medium 17 moves away from the terminal 911, the terminal 911 moves following the terminal 17A, and the contact between the terminal 17A and the terminal 911 is reached. Is easily maintained.

  In this embodiment, the storage medium 17 is attached to the member (operation member 360) provided with the insertion portion 361. In other words, the insertion portion 361 and the storage medium 17 are provided on a common member (component). Here, each of the insertion unit 361 and the storage medium 17 can be provided on different members (parts). However, in this case, the storage medium 17 can move more easily with respect to the insertion unit 361 than in the case where the insertion unit 361 and the storage medium 17 are provided on a common member. End up. And if it becomes easy to move in this way, the displacement of the storage medium 17 is likely to occur, and the terminal 17A of the storage medium 17 becomes easier to move with respect to the terminal 911 of the holding member 910. For this reason, in this embodiment, the insertion portion 361 and the storage medium 17 are provided for one (common) member (operation member 360).

  In the present embodiment, as shown in FIG. 3, the insertion unit 361 and the storage medium 17 are arranged in a state where the insertion unit 361 and the storage medium 17 are brought close to each other. Thus, when the insertion portion 361 and the storage medium 17 are arranged close to each other, the displacement of the storage medium 17 with respect to the insertion portion 361 is less likely to occur than when the insertion portion 361 and the storage medium 17 are arranged apart from each other. . In the present embodiment, as shown in FIG. 3, the storage medium 17 is arranged in the area 3 </ b> A located between the two insertion portions 361. As described above, when a plurality of the insertion portions 361 are provided and the storage medium 17 is provided between the insertion portions 361, the case where the number of the insertion portions 361 is single or the storage medium 17 is not located between the insertion portions 361 is compared. The displacement of the storage medium 17 with respect to the insertion portion 361 is less likely to occur.

  As shown in FIG. 7, the insertion portion 361 and the storage medium 17 are provided on one side of the operation member 360 (toner cartridge 80). In addition, both the insertion portion 361 and the storage medium 17 are provided on the same surface among the plurality of surfaces provided on the operation member 360. Here, for example, the insertion portion 361 can be provided on the first side surface 368 side in FIG. 7 and the storage medium 17 can be provided on the second side surface 369 (side surface opposite to the first side surface 368) side in FIG. However, in this case, the displacement of the storage medium 17 with respect to the insertion portion 361 is more likely to occur than when both the insertion portion 361 and the storage medium 17 are provided on one side surface side. Therefore, in the present embodiment, the insertion portion 361 and the storage medium 17 are provided on one side surface (the same side surface) of the operation member 360.

  Further, the storage medium 17 can be provided on one end side in the longitudinal direction of the toner cartridge 80 and the insertion portion 361 can be provided on the other end side in the longitudinal direction of the toner cartridge 80. In this case, the storage medium 17 and the insertion portion 361 The distance becomes larger. In such a case, similarly to the above, the displacement of the storage medium 17 with respect to the insertion portion 361 is likely to occur. Therefore, in the present embodiment, the storage medium 17 and the insertion portion 361 are provided on the same end side of the two end portions.

  Furthermore, in this embodiment, the storage medium 17 and the insertion portion 361 are provided on the opposite side of the toner cartridge 80 from the side on which the rotation member 301 (see FIG. 2) is provided. In the toner cartridge 80, the vibration tends to increase on the side where the rotating member 301 is provided (the side receiving the driving force). Therefore, in the present embodiment, the storage medium 17 and the insertion portion 361 are provided on the opposite side of the toner cartridge 80 from the side on which the rotation member 301 is provided. In the above description, the cross-sectional shape of the insertion portion 361 is a T-shape, but is not limited to a T-shape, and may be a rectangle, a triangle, an ellipse, a circle, or the like. In the above description, the storage medium 17 is provided in the toner cartridge 80. However, this is an example, and the storage medium 17 may be provided in the process cartridge 100 or the like. In addition, the configuration described above can be applied to other detachable bodies such as the process cartridge 100.

In addition, the insertion portion 361 can be provided with a restriction portion that restricts the movement of the insertion portion 361 relative to the positioning portion 920. In addition, a restricting portion that restricts the movement of the insertion portion 361 in the direction in which the insertion portion 361 is removed from the insertion port 921 can be provided for the insertion portion 361.
FIG. 13 is a view for explaining a restricting portion provided in the insertion portion 361.
As shown in FIG. 6A, the insertion portion 361 has a first base portion 361G provided along the longitudinal direction of the toner cartridge 80 and a gap between the first base portion 361G. A second base portion 361H that is disposed and is provided along the longitudinal direction of the toner cartridge 80 is also provided.

  Further, it is provided connected to the first base portion 361G and is provided connected to the first piece portion 361J and the second base portion 361H, which are separated from the second base portion 361H side toward the downstream side in the insertion direction of the toner cartridge 80, and the toner. A second piece 361K is provided that moves away from the first base 361G side toward the downstream side in the insertion direction of the cartridge 80. Further, the third piece 361L and the second piece 361K are provided connected to the first piece 361J and approach the side where the second base 361H is provided toward the downstream side in the insertion direction of the toner cartridge 80. A fourth piece portion 361M is provided that is connected to the first cartridge portion 341M and is closer to the side where the first base portion 361G is provided toward the downstream side in the insertion direction of the toner cartridge 80. Here, in the present embodiment, the tip of the third piece 361L and the tip of the fourth piece 361M are connected.

  Here, in the present embodiment, the first top portion 361N located at the connection portion between the first piece portion 361J and the third piece portion 361L, and the first portion located at the connection portion between the second piece portion 361K and the fourth piece portion 361M. The separation distance from the two top portions 361 </ b> P is larger than the width L of the insertion port 921. For this reason, when the insertion part 361 inserted in the insertion port 921 moves in the direction in which it is pulled out, the top parts 361N and 361P come into contact with the positioning part 920. As a result, the movement of the insertion portion 361 in the direction in which the insertion portion 361 is removed is restricted.

  When the user installs the toner cartridge 80, the first base portion 361G, the second base portion 361H, and the first piece portion 361J to the fourth piece portion 361M are moved when the insertion portion 361 comes into contact with the positioning portion 920. The first top portion 361N and the second top portion 361P approach each other due to elastic deformation. As a result, the insertion portion 361 passes through the insertion port 921. Further, when the toner cartridge 80 is removed by the user, the first base portion 361G, the second base portion 361H, and the first piece portion 361J to the fourth piece portion 361M are elastically deformed when the insertion portion 361 contacts the positioning portion 920. The first top portion 361N and the second top portion 361P approach each other. As a result, the insertion portion 361 passes through the insertion port 921. In addition, although the case where the front-end | tip part of the 3rd piece part 361L and the front-end | tip part of the 4th piece part 361M were connected was illustrated above, as shown to the same figure (B), the front-end | tip of the 3rd piece part 361L is shown. You may make it space | separate a part and the front-end | tip part of the 4th piece part 361M.

FIG. 14 is a perspective view of the housing member 900 as viewed from above the housing member 900. FIG. 15 is a top view of the housing member 900.
As shown in FIG. 14, as described above, the holding member 910 is provided on the inlet side of the housing member 900 where the insertion of the toner cartridge 80 is started. As described above, the holding member 910 is provided with the terminal 911 that contacts the terminal 17A (see FIG. 3) formed on the storage medium 17. In FIG. 14, a rotating member 990 that is driven to rotate by a motor (not shown) and rotates the rotating member 301 (see FIG. 2) provided in the toner cartridge 80 is also displayed.

  In this embodiment, as shown in FIGS. 14 and 15, a first flat surface 941 is formed on the back side of the housing member 900 (the back side in the insertion direction of the toner cartridge 80) and on the bottom of the housing member 900. Has been. Further, an opening 942 is formed in the first flat surface 941. Here, in this embodiment, the toner discharged from the toner cartridge 80 is supplied to a toner conveyance mechanism (not shown) provided below the storage member 900 through the opening 942.

  Further, a second flat surface 943 located at a position lower than the first flat surface 941 is provided on the upstream side in the insertion direction of the toner cartridge 80 from the first flat surface 941. Further, a third flat surface 944 located at a position lower than the second flat surface 943 is provided upstream of the second flat surface 943 in the insertion direction of the toner cartridge 80. Also, a first connection surface 945 provided along the vertical direction and connecting the first flat surface 941 and the second flat surface 943, and a second flat surface 943 and a third flat surface 944 provided along the vertical direction are also provided. A second connection surface 946 to be connected is provided.

  The accommodating member 900 is provided with a first opposing piece 947 and a second opposing piece 948 that are disposed with a gap between the accommodating member 900 and the first flat surface 941 and face the first flat surface 941. Here, the first opposing piece 947 and the second opposing piece 948 are provided along the insertion direction of the toner cartridge 80 (the longitudinal direction of the housing member 900). The opening 942 is disposed between the first facing piece 947 and the second facing piece 948.

  Furthermore, in the present embodiment, a first protruding piece 951 and a second protruding piece 952 that protrude from the first connection surface 945 toward the upstream side in the insertion direction of the toner cartridge 80 are provided. Here, the first protruding piece 951 and the second protruding piece 952 are provided so as to be elastically deformable, and can be bent in a direction perpendicular to the insertion direction of the toner cartridge 80. Further, the first projecting piece 951 and the second projecting piece 952 are provided such that their tip portions are positioned on the upstream side in the insertion direction of the toner cartridge 80 from the second connection surface 946. In the present embodiment, a gap is formed between the first protruding piece 951 and the third flat surface 944. Further, a gap is formed between the second protruding piece 952 and the third flat surface 944.

  Further, as shown in FIG. 15, each of the first projecting piece 951 and the second projecting piece 952 protrudes on the moving path of the first shutter 302 (see FIG. 5) at the tip thereof, and moves the first shutter 302 ( A restriction protrusion 953 is provided for restricting (described later) retreat. Further, each of the first projecting piece 951 and the second projecting piece 952 is moved by being pressed by a pressing projection 307 (see FIG. 5) provided in the toner cartridge 80, and the first projecting piece 951 and the second projecting piece 951 are moved. Displacement protrusions 954 for displacing the protruding pieces 952 are provided.

  Here, the displacement protrusion 954 has an inclined surface 954A that approaches the central side of the housing member 900 as it goes upstream in the insertion direction of the toner cartridge 80, and the inclined surface 954A is pressed by the pressing protrusion 307. As a result, the first projecting piece 951 and the second projecting piece 952 are displaced. More specifically, the first projecting piece 951 and the second projecting piece 952 are displaced so that the first projecting piece 951 and the second projecting piece 952 are separated from each other.

  Next, the movement of each part when the toner cartridge 80 is inserted into the housing member 900 will be described with reference to FIG. When the insertion of the toner cartridge 80 into the housing member 900 is started, the second shutter 303 moves toward the back side of the housing member 900 as the toner cartridge 80 moves. The second shutter 303 has a gap formed between the first protruding piece 951 and the third flat surface 944 and a gap formed between the second protruding piece 952 and the third flat surface 944. While entering, it hits the second connection surface 946.

  As a result, the movement of the second shutter 303 is restricted and the second shutter 303 remains on the third flat surface 944. After the second shutter 303 hits the second connection surface 946, a load is applied to the cylindrical member 300 of the toner cartridge 80 from the extending coil spring SP (see FIG. 4). Therefore, after the second shutter 303 hits the second connection surface 946, the user pushes the toner cartridge 80 toward the back side of the image forming apparatus 1 with a load larger than this load. In this embodiment, the spring constant of the coil spring SP is set to be small, and the load (biasing force) that acts on the cylindrical member 300 of the toner cartridge 80 from the coil spring SP is small. For this reason, in this embodiment, the user hardly feels the load from the coil spring SP. In other words, the operation feeling felt by the user is not changed.

  Thereafter, as the toner cartridge 80 is further moved, the first shutter 302 moves toward the back side of the housing member 900. Then, the first shutter 302 enters between the first protruding piece 951 and the second protruding piece 952, and the first shutter 302 hits the first connection surface 945 (an example of the second butting portion). Become. Thereby, the movement of the first shutter 302 is restricted, and the first shutter 302 remains on the second flat surface 943 and between the first protruding piece 951 and the second protruding piece 952. Thereafter, in this embodiment, the discharge port 305 is moved by the further movement of the toner cartridge 80, and the discharge port 305 is positioned on the opening 942. As a result, the toner inside the toner cartridge 80 is supplied to the main body side of the image forming apparatus 1.

  Note that after the first shutter 302 hits the first connection surface 945 and the first shutter 302 stops, the cylindrical member 300 moves with respect to the first shutter 302. At this time, friction (sliding) occurs between the first shutter 302 and the first opposing piece 373 (see FIG. 6). For this reason, after the first shutter 302 hits the first connection surface 945, sliding resistance acts on the cylindrical member 300 from the first shutter 302, and the operation load required for inserting the toner cartridge 80 is increased. Becomes larger. In the present embodiment, the sliding resistance that acts on the cylindrical member 300 from the first shutter 302 is greater than the load (biasing force) that acts on the cylindrical member 300 of the toner cartridge 80 from the coil spring SP. Is also getting bigger.

  Here, FIG. 16 is a diagram showing an internal state of the housing member 900 after the insertion of the toner cartridge 80 is completed. In the drawing, a first shutter 302 and a second shutter 303 provided in the toner cartridge 80 are also displayed.

  As described above, when the toner cartridge 80 is inserted, the gap formed between the first projecting piece 951 and the third flat surface 944 and the space between the second projecting piece 952 and the third flat surface 944 are disposed. The second shutter 303 enters the gap formed at. Further, the second shutter 303 comes into contact with the second connection surface 946. Accordingly, the movement of the second shutter 303 is restricted, and the second shutter 303 remains on the near side of the second connection surface 946 as shown in FIG. Further, as described above, the further insertion of the toner cartridge 80 causes the first shutter 302 to abut against the first connection surface 945. As a result, the movement of the first shutter 302 is restricted, and the first shutter 302 remains on the near side of the first connection surface 945 as shown in FIG.

  As shown in FIG. 16, a gap is formed between the side piece 303 </ b> B of the second shutter 303 and the first protruding piece 951 in a direction orthogonal to the insertion direction of the toner cartridge 80. Further, a gap is also formed between the side piece 303C of the second shutter 303 and the second protruding piece 952. Here, when the toner cartridge 80 is pulled out from the image forming apparatus 1, the first protruding piece 951 and the second protruding piece 952 move away from each other (described later). In this case, if the gap is not formed between the side piece 303B and the first protruding piece 951 and between the side piece 303C and the second protruding piece 952, the first protruding piece 951 and The second protruding piece 952 and the second shutter 303 interfere with each other. In this case, it is difficult to retract the first shutter 302, and it is difficult to pull out the toner cartridge 80. Therefore, in the present embodiment, the gap as described above is formed.

  Although not described above, when the toner cartridge 80 is inserted into the housing member 900, the toner cartridge is inserted into a gap formed between the first facing piece 947 (see FIG. 14) and the first flat surface 941. A first opposing piece 373 (see FIG. 6) formed at 80 enters. The elastic member 306 (see FIG. 6) also enters the gap. Further, when the toner cartridge 80 is inserted into the housing member 900, the second cartridge formed in the toner cartridge 80 is formed in the gap formed between the second facing piece 948 (see FIG. 14) and the first flat surface 941. The opposing piece 374 (see FIG. 6) enters. The elastic member 306 also enters this gap.

  In this embodiment, the elastic member 306 is moved by the first opposing piece 373 and the elastic member 306 entering the gap formed between the first opposing piece 947 and the first flat surface 941. It is designed to be compressed. Further, the elastic member 306 is compressed as the second opposing piece 374 and the elastic member 306 enter the gap formed between the second opposing piece 948 and the first flat surface 941. It has become. In the present embodiment, the elastic member 306 is compressed in this way, so that the periphery of the discharge port 305 (see FIG. 5) and the opening 942 (see FIG. 14) is sealed, and the inside of the housing member 900 is filled. Toner leakage is suppressed.

Next, the movement of each part when the toner cartridge 80 is pulled out will be described with reference to FIG.
When the extraction of the toner cartridge 80 is started, the first opposing piece 373, the second opposing piece 374, and the elastic member 306 shown in FIG. 6 move toward the upstream side in the extraction direction of the toner cartridge 80. When the first opposing piece 373, the second opposing piece 374, and the elastic member 306 reach the stopped first shutter 302, the first opposing piece 373, the second opposing piece 374, and the elastic member 306 are It enters the inside of the first shutter 302. More specifically, it enters between the shutter body 302A (see FIG. 6) and the first opposing piece 302B, and enters between the shutter body 302A and the second opposing piece 302C. Further, the discharge port 305 provided in the toner cartridge 80 also moves toward the first shutter 302, so that the discharge port 305 is covered with the first shutter 302.

  Until the discharge port 305 is covered by the first shutter 302, the movement of the first shutter 302 is restricted by the restriction protrusion 953 (see FIG. 15) formed on the first protrusion piece 951 and the second protrusion piece 952. It has become so. In other words, until the discharge port 305 is covered with the first shutter 302, the first shutter 302 comes into contact with the restricting protrusion 953 (an example of the abutting portion), and the movement of the first shutter 302 is restricted. Yes. In this embodiment, after the discharge port 305 is covered by the first shutter 302, the pressing protrusion 307 (see FIG. 5) provided on the toner cartridge 80 abuts against the displacement protrusion 954 (see FIG. 15). Thereby, the 1st protrusion piece 951 and the 2nd protrusion piece 952 move to the direction which mutually leaves | separates, and the restriction | limiting of the movement of the 1st shutter 302 is cancelled | released. As a result, the backward movement of the first shutter 302 is started. In other words, the first shutter 302 moves along with the retreating cylindrical member 300. The pressing protrusion 307 can be regarded as a retracting part for retracting the restricting protrusion 953 functioning as an abutting part from the moving path of the first shutter 302.

  When the first shutter 302 starts to be retracted, the first shutter 302 is covered with the second shutter 303. In addition, the second shutter 303 is pressed toward the second connection surface 946 by being pulled by the coil spring SP, and remains in a certain position. More specifically, the second shutter 303 is in a state of being abutted against the abutting portion and the second connecting surface 946 functioning as the first abutting portion by being pulled by the coil spring SP, and is in a fixed position. Stays. For this reason, the first shutter 302 moves relative to the second shutter 303, and the first shutter 302 is covered with the second shutter 303. Thereafter, with the further movement of the toner cartridge 80, the second shutter 303 moves accompanying the cylindrical member 300, and the second shutter 303 moves away from the second connection surface 946. Thereafter, the toner cartridge 80 is further pulled out while the first shutter 302 is covered by the second shutter 303.

  Here, in the present embodiment, as described above, the second shutter 303 is separated from the second connection surface 946 after the first shutter 302 is covered with the second shutter 303. In other words, the end portion 302G of the first shutter 302 (the end located upstream in the pulling direction of the toner cartridge 80) above the joint portion (see 16A in FIG. 16) between the second shutter 303 and the second connection surface 946. The second shutter 303 is separated from the second connection surface 946 after the first portion passes.

  Here, before the first shutter 302 is covered by the second shutter 303 (before the end portion 302G passes above the joint portion), the second shutter 303 is separated from the second connection surface 946. The toner falling from the first shutter 302 or the like may enter a gap formed between the second shutter 303 and the second connection surface 946. In other words, the toner may be discharged into the housing member 900. Therefore, in the present embodiment, the second shutter 303 is separated from the second connection surface 946 after the first shutter 302 is covered by the second shutter 303.

  Although not described above, as shown in FIG. 16, a linear protrusion provided on the inner surface of the second shutter 303 along a direction orthogonal to the longitudinal direction of the toner cartridge 80 (direction intersecting). A portion 303T is provided. In other words, a protrusion 303 </ b> T extending in a direction perpendicular to the longitudinal direction of the toner cartridge 80 is provided on the back surface (facing surface facing the first shutter 302) of the facing piece 3031 (see FIG. 5) of the second shutter 303. ing. In addition, on the back surface of the facing piece 3031 of the second shutter 303, a protruding portion 303T formed so as to go from the side on which the one side piece 303B is provided to the side on which the other side piece 303C is provided. Is formed. Note that a plurality of the protruding portions 303T are provided in a state of being aligned in the longitudinal direction of the toner cartridge 80. Here, toner may adhere to the inner surface of the second shutter 303. However, if the inner surface of the second shutter 303 is smooth, the toner is likely to move, and the front end portion of the second shutter 303 (see also FIG. 2). ) Makes it easy for the toner to fall. For this reason, in this embodiment, the movement of the toner is restricted by providing a plurality of protrusions 303T.

  Although not described above, in the present embodiment, the shape of the front end portion of the toner cartridge 80 is made to follow the shape of the inlet portion side of the housing member 900 where insertion of the toner cartridge 80 is started. . More specifically, as shown in FIG. 9, the bottom plate 970 and the one side plate 971 of the storage member 900 are orthogonal to each other, and the bottom plate 970 and the other side plate 972 are orthogonal to each other. Two corners 974 and 975 are formed on the inlet side where the insertion of the cartridge 80 is started.

  Also, as shown in FIG. 2, the opposing piece 3031 and one side piece 303B are orthogonal to each other, and the opposing piece 3031 and the other side piece 303C are orthogonal to the second shutter 303 located at the tip of the toner cartridge 80. As a result, two corners 308 and 309 (see FIG. 2) are formed at the tip of the toner cartridge 80. When the accommodating member 900 and the toner cartridge 80 are formed in such a shape, an insertion error of the toner cartridge 80 is less likely to occur. More specifically, for example, it is difficult for the toner cartridge 80 to be inserted in an upside down state.

  Here, as described above, the toner cartridge 80 attached to the image forming apparatus 1 is often provided with a shutter that covers the toner discharge port. However, the toner often adheres to the shutter, and the user's clothes, etc. The toner tends to adhere to the surroundings. In addition, the toner cartridge 80 may be shaken by the user before the toner cartridge 80 is used. At this time, if the toner cartridge 80 is shaken with the shutter portion held, the shutter may open and the toner inside may leak out.

  Therefore, in this embodiment, in addition to the first shutter 302 that covers the discharge port 305 from which the toner is discharged, a second shutter 303 that covers the first shutter 302 is provided. In addition, it is preferable to make the color of the outer surface of the second shutter 303 different from the color of the outer surface of the cylindrical member 300. In this case, the possibility that the second shutter 303 is recognized by the user is increased, and an unintended operation of the second shutter 303 is suppressed. In the present embodiment, the toner cartridge 80 is configured as described above, so that the first shutter 302 and the second shutter 303 are opened only by inserting the toner cartridge 80 linearly in one direction. Similarly, the first shutter 302 and the second shutter 303 are closed only by pulling out the toner cartridge 80 linearly in one direction. In addition, in the toner cartridge 80 in the present embodiment, the two shutters are opened and closed without performing a complicated operation such as rotating the toner cartridge 80 in the circumferential direction.
